    let me know when you have one then it should be pretty obvious what to do hint: it involves tangent

    you are looking for \(h\) \[\tan(26^\circ)=\frac{h-1.65}{90}\] which is really another way of saying multiply \[90\times \tan(26^\circ)\] and add \(1.65\) to the result to get \(h\)

    now you are really being silly a) you cannot find \(\tan(26^\circ)\) by hand b) of course you have a calculator you have almost an infinite number of calculators how did you get to openstudy?
